Bones visible thru Skin

[WanderingVet]

Take a closer look at the upper left of front of camper and upper right of rear of camper. I can see the frame thru the skin. Can someone tell me what they think is wrong? Is it paint job failure? What can it be?

[Jkwilson]

Is there condensation on the surface?

[Cate&Rob]

Completely normal. Condensation will stay on the skin over the cooler aluminum frames in the morning.

It's normal. Here is mine.

Take a picture when it happens. It will help you identify the frame location if you ever need it.

And mine . . .

It's indicative of how the interior heat transmits through the frame.

If the surface temperature of the framing is below the dew point, the area of the framing will condensate. See relative humidity, dew point and condensation.

In my case there is frost on the siding and not where the frame is. It could happen that way with condensation if the skin is below dew point and the area over the frame is not.

Can work this way as well. Just depends on the surface temp relative to the dew point.

The takeaway on this is that it is normal. But it is quite useful to take pictures of it to tell where your frame is. I have done that to mine as I am considering adding a window to the bedroom. I would want to add in between the frame such that I have a frame on both sides. Also do not want to cut through the frame.

So from my observations on 3 trailers now all by different manufacturers. The framing tends to follow a temperature trend of the inside of the camper. If the inside is cooler than outside, the framing can end up cooler. This is due to the Aluminum transmission of heat. I've seen condensation on the outside in the summer and dry lines in the fall.
